Answer:
Greg opened the door and found his father pacing the kitchen with a worried look in his eye. When he saw Greg, his face broke out into a smile. “Where on earth have . . . ,” he started to say. But then he stopped and pulled Greg toward him in a big bear hug. “Forget it, it doesn’t matter anymore. I’m just glad you’re home,” he said.
Greg looked up at the man he had never understood before. “Thanks, Dad,” he said.
“For what?” his father asked.
Greg smiled, and answered, “Everything.”
